Abstract

ABSTRAK : Penyu laut merupakan hewan yang menghabiskan hampir seluruh hidupnya di bawah permukaan laut. Penyu laut dikategorikan hewan yang terancam punah. Jenis Penyu Lekang (Lepidochelys olivacea) adalah organisme laut yang tergolong dalam kategori terancam punah. Salah satu upaya untuk melestarikan populasi penyu adalah dengan melakukan pelepasan tukik. Namun keberhasilan setelah pelepasan tukik pada umumnya tidak pernah diketahui. Oleh karena itu, perlu adanya usaha untuk mempersiapkan tukik sebelum dilepas ke laut, sehingga membantu tingkat kelangsungan hidup tinggi. Aspek yang sampai saat ini belum diketahui adalah kebutuhan nutrisi yang tepat untuk menunjang pertumbuhan tukik. Penelitian ini bertujuan untuk mengetahui pengaruh pemberian pakan buatan yang berbeda terhadap laju pertumbuhan panjang karapas, lebar karapas, dan bobot pada tukik Penyu Lekang. Penelitian ini dilakukan pada bulan Januari 2016 di Turtle Conservation and Education Center, Bali. Metode penelitian yang digunakan adalah metode eksperimental dengan menggunakan rancangan acak lengkap (RAL) 3 perlakuan dan 3 kali ulangan. Perlakuan yang diberikan berupa perbedaan sumber bahan baku pakan yang berbeda pada tukik adalah A=tepung ikan 40%, B=tepung ikan 35%, dan C=tepung ikan 30%. Jumlah pakan yang diberikan sebesar 5% dari bobot tukik per hari. Pemberian pakan dilakukan 2 kali sehari pada waktu pagi jam 09.00 WITA dan sore hari jam 16.00 WITA. Pergantian air dilakukan setiap hari pada pagi hari jam 07.00 WITA. Hasil pemberian pakan buatan dengan jumlah tepung ikan yang berbeda memberikan pengaruh sangat nyata (p<0,01) terhadap laju pertumbuhan spesifik panjang karapas, lebar karapas, dan bobot tukik Penyu Lekang. Pakan buatan yang paling baik di antara perlakuan yang diterapkan dicapai oleh pakan buatan dengan kandungan tepung ikan 40%. Pakan buatan dengan kandungan tepung ikan 40% menghasilkan tingkat laju pertumbuhan spesifik panjang karapas 0,48%/hari, lebar karapas 0,56 %/hari, dan berat tukik 1,13 %/hari. ABSTRACT : A sea turtle is an animal that spends most of its life under the sea. Sea turtles also belongs to the category of extinct animals. Olive ridley sea turtle (Lepidochelys olivacea) is a marine organism belonging to the endangered category. One of the efforts to conserve the turtle population is to release the hatchlings. But the succeed after releasing the hatchlings is generally not recognized. Therefore, there is a need to prepare for the hatchlings before being released into the sea to help the survival rate improved. An aspect which is still unrecognized is the need to support proper nutrient for the hatchlings growth. This study aimed to determine different concentrations in artificial feed to the growth rate of hatchling turtles carapace length, carapace width, and weight. This study was conducted in January 2016 in Turtle Conservation and Education Center, Bali. The method used was an experimental method with completely randomized design three treatments and three replications. The treatment given in the form of different sources of raw materials of different feed to hatchlings is A = the flour fish 40%, B = the flour fish 35%, and C =the flour fish 30%. The weight of the feed given was 5% of the hatchlings weight. The feeding was done twice a day, at 09.00 a.m. and at 04.00 pm. The substitution of water was done every day at 07.00 pm. The analysis result of the artificial feed of flour different fishes exert very real (p<0,01) against growth rate long specific carapace, wide carapace and weights hatchlings olive ridley sea turtles. Artificial feed the best between those who applied reached by feed artificially with the flour fish 40 %. Feed artificially with the flour fish 40 % generate a level of growth rate long specific carapace 0,48 %/day, wide carapace 0,56 %/day and heavy hatchlings 1,13 %/day.

Abstract

ABSTRAK: Rajungan (P. pelagicus, Linnaeus, 1758) adalah salah satu hasil perikanan utama di Betahwalang, Demak. Penangkapan rajungan diduga dilakukan secara intensif oleh nelayan di Des Betahwalang, maka diperlukan langkah pengelolaan yang tepat untuk menjaga kelestarian dan konservasi rajungan. Informasi aspek morfometri rajungan bias digunakan sebagai salah satu acuan dalam pengelolaan rajungan berkelanjutan. Tujuan penelitian adalah untuk mengkaji tingkat kematangan gonad dan morfometri rajungan yang dilaksanakan pada bulan Juli – September 2019 di Desa Betahwalang, Demak. Penelitian menggunakan metode survey dengan analisis yang bersifat deskriptif yang dilakukan secara “time-series”. Pengamatan sampel rajungan sebesar 10% dari hasil tangkapan yang didaratkan oleh setiap nelayan di pengepul rajungan. Total rajungan yang diamati 5.480 ekor terdiri dari betina 2.960 ekor dan jantan 2.388 ekor. Hasil penelitian menunjukkan pertumbuhan rajungan jantan bersifat allometrik positif, sedangkan rajungan betina cenderung bersifat allometrik negatif dengan seks rasio relatif seimbang. Rajungan betina diduga mengalami pertama kali matang gonad pada selang kelas lebar karapas 70 – 79 mm. Sampel pengamatan fekunditas dan kematangan telur pada 126 ekor rajungan betina bertelur. Kematangan telur dilihat dari pigmen warnanya secara berurutan mulai pigmen warna kuning, orange, coklat dan hitam, serta berdasarkan ukuran diameter telur. Fekunditas telur memiliki korelasi yang sangat kuat terhadap lebar karapas yang berarti semakin besar ukuran rajungan, maka jumlah telur semakin banyak. Selama penelitian masih ditemukan rajungan “undersize” sebesar 18% (981 ekor) dan rajungan betina bertelur sebesar 24% (716 ekor), yang berarti nelayan di Desa Betahwalang belum menerapkan kriteria dan ukuran layak tangkap sesuai dengan peraturan yang berlaku.ABSTRACT: Blue swimming crab (P. pelagicus, Linnaeus, 1758) is one of main fisheries products in Betahwalang, Demak. High-intensity levels of catching the blue swimmer crab by fisherman may need sustainable management to protect and conserve the population. The purpose of this study was to determine about gonad maturity level and morphometrical aspect of blue swimming crab started from July – September 2019. There’s a descriptive survey method used in this study with time-series observations. The sample size is about 10% of the total number landed crab from each fisherman. The total sample are 5.348 that consist of 2.960 female crabs and 2.388 male crabs. The results showed the male crabs has a positive allometric on growth parameters, but the females have an allometric positive and negative growth parameters, and balanced sex-ratio. Female crabs may reach the first matured gonad level between 70 – 79 mm of carapace width. Fecundity and egg’s maturity observation used 126 berried female crabs. The egg’s maturity based on the pigment color started from yellow, became orange, brown and black also by egg diameter increase. The analysis showed that female crab fecundity has a strong correlation to the increase of carapace width, which means carapace width increase followed by egg’s amount increasing. During the study, it was found about 18% (981 crabs) the undersize crabs (<100 mm) and 24% (716 crabs) the berried female crabs, which means the Betahwalang fisherman hasn’t applied the rule yet.

Abstract

Echinodermata merupakan biota yang dapat ditemukan hampir di semua ekosistem laut. Echinodermata cukup melimpah keberadaannya di kawasan terumbu karang, hal ini karena terumbu karang berperan sebagai tempat berlindung dan mencari makan bagi Echinodermata. Dalam rantai makanan, Echinodermata memiliki peranan sebagai pemakan seston atau detritus, dan merombak sisa bahan organik. Echinodermata juga berperan sebagai bioindikator parameter kualitas perairan. Penelitian ini bertujuan untuk mengetahui kelimpahan Echinodermata yang terdapat di Pantai Krakal, Gunung Kidul, Yogyakarta dan Pantai Pailus, Jepara, Jawa Tengah. Metode yang digunakan dalam penelitian ini yaitu metode deskriptif. Pengambilan sampel pada penelitian ini menggunakan metode transek kuadran dengan ukuran 1x1m. Hasil pengamatan di Pantai Krakal ditemukan 2 kelas dari filum Echinodermata, antara lain 3 species dari Kelas Ophiuroidea yaitu Ophiocoma erinaceus, Ophiocoma scolopendrina, Ophiarachna affinis, dan 3 species dari Kelas Echinoidea yaitu Echinometra viridis, Echinometra oblonga, dan Stomopneustes variolaris. Sedangkan jenis Echinodermata yang ditemukan di Pantai Pailus ditemukan 1 Kelas Echinodermata yaitu Holothuridea yang terdiri dari 3 spesies, yaitu Holothuria atra, Holothuria scabra, dan Holothuria leucospilota. Hasil penelitian menunjukkan kelimpahan individu tertinggi penelitian di Pantai Krakal adalah Ophiocoma scolopendrina (7,05 ind/m²),sedangkan kelimpahan individu tertinggi di Pantai Pailus adalah Holothuria scabra (2,13  ind/m²). Echinodermata is a biota that can be found almost in all marine ecosystems. Echinodermata quite abundant presence in the area coral reefs, because it serves as shelter and feed for Echinodermata. In the food chain, Echinodermata has a role as a seston eater or dentrite, and remodel the rest of the organic material. Echinodermata also serves as a bioindicator of water quality parameters. This study aims to determine the abundance of Echinodermata found in Krakal Beach, Gunung Kidul, Yogyakarta and Pailus Beach, Jepara, Central Java. The method used in this research was descriptive method. Sampling in this research used quadrant transect method with size 1x1m.

Abstract

Seaweed is a low-level photosynthetic organism that has no stem, leaves, or root. Seaweeds are commonly used as food and as an ingredient for the food industry, pharmaceutical industry, cosmetics industry, and other industries. Caulerpa is potential to be cultivated because it has been known and liked by people. Beside, Caulerpa also has economic value for people. This kind of seaweed grows seasonally, but sometimes Caulerpa cannot be found in the water even during the season because its growth highly depends on the environment’s condition. This situation leads to Caulerpa production shortages. Hence, Caulerpa cultivation is necessary. The purpose of this research is to know the effect of adding NPK and urea at different concentration to the growth rate of Caulerpa racemosa var. uvifera. This research was conducted from May till July 2011 at Laboratory of Marine Science, Faculty of Fisheries and Marine Science Diponegoro University, Teluk Awur, Jepara. C. racemosa var. uvifera samples were taken from Bandengan coastal waters, Jepara the method used in this research was experimental method with a completely randomized block design. This research used 5 of treatments, each repeated 3 times. The cultivation medium used was sea water that has been deposited for 24 hours, with fertilizers added in different concentration: medium A was not added with fertilizers, medium B was added with 1.60 ppm of NPK fertilizers and 5.40 ppm of urea fertilizers, medium C was added with 4.93 ppm of NPK fertilizers and 10.82 ppm of urea fertilizers, medium D was added with 8.26 ppm of NPK fertilizers and 16.26 ppm of urea fertilizers, and medium E was added with 11.60 ppm of NPK fertilizers and 21.70 ppm of urea fertilizers. The data gained were wet weight of seaweed and water quality of the cultivation medium. The data was analyzed using ANOVA. The result showed that the addition of NPK and urea fertilizers in different concentration gave different effect (p < 0.01) among each treatment. The highest specific growth rate of C. racemosa var. uvifera was achieved in medium D (6.86 % per day with 8.26 ppm of NPK and 16,26 ppm of urea addition) while the lowest specific growth rate was obtained in medium A (5.97% per day with no NPK and urea addition).

Samples were extracted by Na2CO3 7 % solution under diffirencees temperature from 40 ºC - 80 ºC, temperature range 10 °C, each treatment 3 times replicated. Correlation between extraction temperature and sodium alginate qualities were showed positive linier model regression for rendement sodium alginate, negative linier regression model for viscosity and moisture, but not significant for ash content. The result showed the highest rendement of sodium alginate was produced on temperature of 80 ºC, that was 28.31% ± 0.48%. The lowest moisture was produced on temperature of 80 ºC, that was 14.97 ± 1.55%. Highest viscosity was produced on temperature 40 ºC, that was 27.25 ± 0.93 cPs.

Abstract

Lamun jenis Enhalus acoroides merupakan salah satu komponen keanekaragaman hayati yang tumbuh di Perairan Kartini dan Teluk Awur. Aktivitas pariwisata, pelabuhan, pembuatan, pengecatan, pengelasan, pembersihan dan lalu lintas kapal nelayan menjadi penyebab terakumulasinya logam berat di perairan. Logam berat Pb merupakan logam berat beracun dan berbahaya, bahan pencemar dan cenderung mengganggu kelangsungan hidup organisme perairan. Tujuan penelitian ini ialah mengetahui dan menganalisis kandungan logam berat Pb pada air, sedimen dan lamun Enhalus acoroides (akar dan daun) di Perairan Kartini dan Teluk Awur, Jepara, serta mengetahui tingkat pecemarannya berdasarkan baku mutu. Penelitian ini menggunakan metode deskriptif, sedangkan metode penentuan lokasi menggunakan metode purposive sampling. Hasil penelitian menunjukkan kandungan logam berat Pb air di Perairan Kartini sebesar 0,181-0,316 mg/l dan Perairan Teluk Awur sebesar 0,001-0,157 mg/l. Kandungan logam berat Pb sedimen di Perairan Kartini sebesar 2,424-3,463 mg/kg dan Perairan Teluk Awur sebesar 2,347-2,496 mg/kg. Kandungan logam berat Pb Lamun Enhalus acoroides pada akar di Perairan Kartini sebesar 0,918–1,854 mg/kg dan Perairan Teluk Awur sebesar 0,906–1,492 mg/kg. Kandungan logam berat Pb Lamun Enhalus acoroides pada daun di Perairan Kartini sebesar 0,764–1,458 mg/kg dan Perairan Teluk Awur sebesar 0,674–1,040 mg/kg. Enhalus acoroides seagrass as a component of biodiversity that grows in the waters of Kartini and Teluk Awur. Activities in these waters include tourism, ports, manufacture, painting, welding, cleaning and traffic of fishing vessels to cause of accumulated heavy metals in the waters. Heavy metal Pb is a toxic and dangerous heavy metal, polluting material and tends to interfere with the survival of aquatic organisms. The purpose of this study was to determine and analyze the Pb heavy metal content in water, sediment and seagrass Enhalus acoroides (roots and leaves) in Kartini and Teluk Awur waters, Jepara, and to determine the level of pollution based on quality standards. This research uses descriptive method, while the location determination method uses purposive sampling method. The results showed that the heavy metal Pb water content in Kartini waters was 0.181 mg/l - 0.316 mg/l and Teluk Awur waters was 0.01-0.157 mg/l. The heavy metal content of Pb sediment in Kartini waters is 2,424-3,463 mg/kg and Teluk Awur waters was 2,347-2,496 mg/kg. The heavy metal content of Pb in Enhalus acoroides in the roots of Kartini waters was 0.918-1.854 mg/kg and Teluk Awur waters was 0.906-1.492 mg/kg. Heavy metal content of Pb in Enhalus acoroides in leaves in Kartini waters was 0.764 mg/kg - 1.458 mg/kg and Teluk Awur waters was 0.674-1.040 mg/kg
